The optical pseudo random signals produced by pseudo random signal generator and electro-optic modulator in traditional photonic-assisted compression sampling method are replaced by optical chaotic signals generated by photoelectric oscillator. The optoelectronic oscillator simulation system is set, and produces optical chaotic signal, whose bandwidth reaches 30 GHz. Based on 1.25 GHz low-speed analog-digital converter, five frequency-random and amplitude-random sparse signals in frequency domain distributed in the 0 to 10 GHz frequency band are compressed, sampled and reconstructed, successfully. At last, a detail comparison on the reconstruction performance between the chaotic photonic compression sampling and traditional methods is shown through numerical simulation. The simulation results show that the former is better than the latter and the chaotic photonic compression sampling method is feasible.
